Its impossible to predict anything in aviation, just be ready to take advantage of any opportunities that interest you. In my time I've seen people predict zero recruitment only to have the busiest year ever or commands are 20 years away then suddenly pilots with 2 years in the airline are on command courses. It could happen that the pilots over 55 suddenly decide to retire and enjoy their health and wealth, or a Korean war could end recruitment for years and throw everything in to chaos.
